What the symbols mean

The neutrino symbols (e.g. n) represent a type of neutrino; it may be a muon or a tau neutrino, or it may be some mixture of the two which is given a numerical label.

	m stands for mass (of the neutrino in this case)
	E stands for energy
	p stands for momentum
	x and L are the distance travelled by the neutrino
	t is the time since the neutrino was produced
	sin and cos are the trigonometric functions sine and cosine

To keep these types of calculations as uncluttered, physicists avoid writing frequently occuring constants like, say, the speed of light ("c"). So for instance, Einstein's famous equation E = mc² can also just be written E = m, if you measure E and m in appropriately chosen units.
